Abstract
Carcinoma ex pleomorphic adenoma is a rare type of cancer of the salivary gland that involves the malignant transformation of a primary or recurrent pleomorphic adenoma, which often metastasises to the lungs or bones, or both. To the best of our knowledge, however, nobody has reported a distant metastasis of this lesion to the brain without such previous metastasis. We report a case in a 64-year-old man.

Abstract
Abstract
BACKGROUND:
The incidence rates of breast cancer (BC) in Asian counties have been rising rapidly. The age-specific female BC incidence rates peak before menopause (around 40-50 years of age) in Asia, however treatment options for pre/perimenopausal patients are limited. Palbociclib (P) is an oral novel cyclin-dependent kinase 4/6 (CDK4/6) inhibitor. The addition of P to endocrine therapy (ET) such as aromatase inhibitor or fulvestrant has been demonstrated improved progression-free survival (PFS) in phase 3 studies PALOMA-2 and PALOMA-3. This study is designed to evaluate efficacy and safety of P plus tamoxifen (TAM) in patients with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced or metastatic BC regardless of menopausal status. This study is conducted as a Clinical Research Collaboration by National Cancer Center Hospital with research funding from Pfizer.
TRIAL DESIGN:
PATHWAY/NCCH1607 is a double-blind, placebo-controlled, randomized, phase 3 study. Patients will be randomized 1:1 to receive either P (125 mg once daily, days1-21 of a 28-day cycle) or placebo in combination with TAM (20 mg once daily, continuously). Pre/perimenopausal women should receive concurrent ovarian function suppression with goserelin. Randomization will be stratified by prior ET for advanced/metastatic BC (1st line ET vs. 2nd line ET) and menopausal status (pre/perimenopausal vs. postmenopausal).
KEY ELIGIBILITY CRITERIA:
Eligible patients include women of any menopausal status with HR-positive, HER2-negative advanced or metastatic BC; candidates to receive TAM as 1st line or 2nd line ET for advanced/metastatic disease; ≥18 years of age; measurable or non-measurable disease (RECIST v.1.1); ECOG performance status 0-1; adequate organ function; have not received treatment with TAM (except for patients who have had more than 12 months from completion of adjuvant therapy with TAM); and have not received any CDK4/6 or phosphoinositide 3-kinase (PI3K) - mammalian target of rapamycin (mTOR) inhibitors.
SPECIFIC AIMS:
The primary endpoint is PFS as assessed by the investigator. Secondary endpoints include overall survival (OS), 1, 2, and 3-year survival probabilities, objective response (OR), duration of response, clinical benefit rate (CBR), pharmacokinetics, safety, and patient-reported outcomes.
STATISTICAL METHODS:
The sample size was determined to detect a 38% reduction in the hazard of disease progression or death in P plus TAM arm with a 1-sided significance level of 2.5% and power of 80%. A stratified log rank test will be used to compare PFS between the 2 treatment arms.
PRESENT ACCRUAL AND TARGET ACCRUAL:
Target accrual of 180 patients will be enrolled within 23 sites among Japan, Korea, Taiwan, and Singapore. As of June 2018, 46 patients have been enrolled.
CONTACT INFORMATION:
This trial is registered at ClinicalTrials.gov NCT03423199 and UMIN000030816. For more information, email NCCH1607_office@ml.res.ncc.go.jp

Abstract
Heparin-binding protein 17 (HBp17)/fibroblast growth factor-binding protein-1 (FGFBP-1) was first purified from medium conditioned by A431 cells for its capacity to bind to fibroblast growth factors 1 and 2 (FGF-1 and -2). Among FGF family members, FGF-2 is a potent mitogen for various cell types, including vascular endothelial cells, fibroblasts, and cancer cells such as oral squamous cell carcinoma (OSCC) cells. Besides being well known in bone metabolism, the active form of vitamin D3, i.e., 1α,25(OH)2D3 (1,25D3), was reported to have protective effects for heart disease and cancer. Previously, we reported that 1,25D3 inhibited HBp17/FGFBP-1 expression in OSCC cell lines through NF-κB inhibition (IκBα activation) and resulted in the inactivation of FGF-2. In this study, we examined the potential anti-tumor effect of ED-71, an analog of 1α,25(OH)2D3, for squamous cell carcinoma cells in vitro and in vivo. The cell lines used were OSCC cell lines (NA-HO-1-n-1 and UE-HO-1-u-1), established from oral cancer patients in our laboratory, and an epidermoid carcinoma/SCC cell line (A431). The growth assay in serum-free culture revealed that ED-71 inhibited the growth of the cancer cell lines in a dose-dependent manner. In addition, ED-71 suppressed HBp17/FGFBP-1 expression by inhibiting the NF-κB pathway as did 1,25D3. Furthermore, a luciferase reporter assay revealed that the promoter activity of HBp17/FGFBP-1 (region between -217 and +61) was down-regulated by ED-71. Oral administration of ED-71 significantly inhibited the growth of A431-derived tumors in athymic nude mice. Immunohistochemical analysis revealed that the expression of HBp17/FGFBP-1, FGF-2, CD31, and Ki-67 in the tumors of ED71-treated group was down-regulated in comparison to control. These results suggest that ED-71 possesses potential anti-tumor activity for SCCs both in vitro and in vivo. This compound may act directly on the tumor cells or on endothelial cells by modulating the tumor microenvironment.

Abstract
The question whether K⁺ depolarization is an appropriate experimental substitute for the physiological nutrient-induced depolarization of the β-cell plasma membrane was investigated using primary mouse β-cells and islets. At basal glucose 40 mM K⁺ induced a massive monophasic response, whereas 15 mM K⁺ had only a minimal insulinotropic effect, even though the increase in the cytosolic Ca²⁺ concentration ([Ca²⁺]i) was not inferior to that by 20 mM glucose. In voltage-clamp experiments, Ca²⁺ influx appeared as nifedipine-inhibitable inward action currents in the presence of sulfonylurea plus TEA to block compensatory outward K⁺ currents. Under these conditions, 15 mM K⁺ induced prolonged action currents and 40 mM K⁺ transformed the action current pattern into a continuous inward current. Correspondingly, 15 mM K⁺ led to an oscillatory increase and 40 mM K⁺ to a plateau of [Ca²⁺]i superimposed on the [Ca²⁺]i elevated by sulfonylurea plus TEA. Raising K⁺ to 15 or 40 mM in the presence of sulfonylurea (±TEA) led to a fast further increase of insulin secretion. This was reduced to basal levels by nifedipine or CoCl₂. The effects of 15 mM K⁺ on depolarization, action currents, and insulin secretion were mimicked by adding 35 mM Cs⁺ and those of 40 mM K⁺ by adding 35 mM Rb⁺, in parallel with their ability to substitute for K⁺ as permeant cation. In conclusion, the alkali metals K⁺, Rb⁺, or Cs⁺ concentration-dependently transform the pattern of Ca²⁺ influx into the β-cell and may thus generate stimuli of supraphysiological strength for insulin secretion.

Abstract
OBJECTIVE This study reports the findings of a Phase I/II, cohort, dose-escalation trial of amrubicin and irinotecan with the support of granulocyte colony-stimulation factor. This study aimed to determine the dose-limiting toxicity of the combination and to define the maximum-tolerated dose, as a recommended dose for Phase II trials. We also sought to obtain preliminary data on the efficacy of this combination as a frontline therapy for extensive-disease small-cell lung cancer. METHODS We included 23 chemo-naïve patients with extensive-disease small-cell lung cancer in the trial. The amrubicin dose was escalated from 35 to 40 mg/m(2) (Levels 1 and 2, respectively) to determine the dose-limiting toxicity, with an unchanged dose of irinotecan at 50 mg/m(2). RESULTS Of nine patients, three experienced dose-limiting toxicities at Level 1 of prolonged Grade 4 neutropenia, Grade 3 febrile neutropenia and Grade 3 febrile neutropenia with Grade 3 diarrhea. At Level 2, two patients experienced dose-limiting toxicities of Grade 4 neutropenia and Grade 3 neutropenia with Grade 4 diarrhea. The maximum-tolerated doses and recommended doses for amrubicin and irinotecan were therefore determined to be 35 and 50 mg/m(2), respectively. The Level 1 trial was then expanded to 21 patients, 14 (70%) of whom showed partial responses to the recommended dose. The median progression-free and overall survival times were 6.37 and 15.21 months, respectively. CONCLUSIONS The combination of amrubicin and irinotecan with the support of granulocyte colony-stimulation factor produced a potent effect in chemo-naïve extensive-disease small-cell lung cancer patients. The use of biomarkers for this regimen may identify patients who are likely to suffer from treatment-ending severe adverse effects.

Abstract
The purpose of this study was to explore the role of the organic anion-transporting polypeptide (OATP) 1A2, which is encoded by SLCO1A2, in the cellular uptake of the Bcr-Abl tyrosine kinase inhibitor imatinib, and the relationship between SLCO1A2 polymorphisms and the pharmacokinetics of imatinib in patients with chronic myeloid leukemia (CML). Imatinib uptake was significantly enhanced in OATP1A2-transfected human embryonic kidney (HEK) 293 cells (P = 0.002). Naringin, an OATP1A2 inhibitor, decreased the transport of imatinib in OATP1A2-transfected HEK293 cells, the human intestinal cell line Caco-2, and K562 CML cells. Linkage disequilibrium was found between the SLCO1A2 -1105G>A and -1032G>A genotypes in 34 CML patients and 100 healthy subjects. Imatinib clearance in CML patients was influenced by the SLCO1A2 -1105G>A/-1032G>A genotype (P = 0.075) and the SLCO1A2 -361GG genotype (P = 0.005). These findings suggest that imatinib is transported into cells by OATP1A2, and that SLCO1A2 polymorphisms significantly affect imatinib pharmacokinetics.

Abstract
Increasing NaCl levels retarded the net photosynthetic rate, biosynthesis of photosynthetic pigments and membrane integrity of maize and sunflower seedlings; a serious effect was exhibited when NaCl was applied at high concentration. On the other hand, the K
+
efflux increased at increasing NaCl levels. In addition, the various salt levels induced considerable variations in the concentrations of sodium, potassium, calcium and magnesium. The vitamins applied were generally effective in partially or completely countering the inhibitory effects of salt stress on net photosynthetic rate, pigments biosynthesis and membrane integrity, exerting a stimulatory action on these parameters, especially in plants subjected to moderate and low salinity levels. The leakage of K
+
was reduced by the application of both ascorbic acid (AsA) and thiamine (B
1
). Soaking the seeds of salt-stressed plants in AsA or B
1
had a favourable effect on the accumulation of certain ions and antagonized or ameliorated the inhibitory effect of salt stress.

Abstract
2506 Background: Erlotinib demonstrates substantial inter-individual differences in response and the development of skin rash (grade≥2) was correlated with efficacy. Erlotinib interacts with its target EGFR and the efflux transporter ABCB1 and ABCG2. EGFR CA repeat is associated with incidence of skin rash. A 421C>A SNP in ABCG2 and 1236C>T, 2677 G>(T/A), and 3435C>T SNPs in ABCB1 are associated with reduced protein expression. The aim of this study was to evaluate the effects of these variants and pharmacokinetics of erlotinib on toxicity grade in Japanese patients treating single agent erlotinib. Methods: Twenty-two patients with NSCLC received erlotinib orally at 150 mg/day and plasma levels of erlotinib were measured on days 1(D1), 8(D8), and stable phase (>day 14) by high-performance liquid chromatography. DNA from plasma was screened for SNPs in the EGFR, ABCB1, and ABCG2 genes using direct nucleotide sequencing or TaqMan assay. Eligibility criteria included: performance status (PS) < 3, age < 75, stage IIIB-IV, and written informed consent. Results: The mean Cmax (±SD) of D1 and D8 were 1.8 ± 1.0 and 3.1 ± 1.4 μg/ml, respectively. Trough concentration (Cmin) at D1 and steady state were 0.9 and 1.7 μg/ml, respectively. Grade 1–2 skin rash or diarrhea occurred in 95% of patients. One patient (Cmax at D1, 3.0 μg/ml) developed interstitial lung disease after continuous treatment with erlotinib for 3 days. The area under curves and Cmax on D1 were correlated with the severity of skin rash (p=0.05 and 0.01), however, Cmin were not correlated. Patients with homozygous variant and heterozygous for ABCB1 1236C>T, 2677 G>(T/A), and 3435C>T genotype as compared to patients carrying the wild-type were associated with higher Cmin at steady state (2.4 vs 1.2 μg/ml, p=0.01). EGFR CA repeat and AGCG2 421C>A genotype were not associated with any pharmacokinetic parameters. All Patients (n=4) with homozygous variant for ABCB1 1236TT- 2677TT/TA/AA-3435TT developed grade≥2 skin rash or diarrhea. Conclusions: The present study suggests that ABCB1 gene polymorphism is associated with the variable toxicity and pharmacokinetics to erlotinib treatment. No significant financial relationships to disclose.

Abstract
2556 Background: There is a close relationship between carboplatin clearance and glomerular filtration rate (GFR). Calvert developed the following formula for the dosing of carboplatin: dose (mg) = target area under the concentration versus time curve (AUC, mg ml-1 min) × [GFR (ml min-1) + 25]. However, this formula has not been evaluated in Japanese population. In this study, we prospectively evaluated renal function and carboplatin clearance in Japanese cancer patients. Methods: GFR was measured by inulin clearance before chemotherapy. The dose of carboplatin was determined by Calvert's formula using adjusted 24-h creatinine clearance (Ccr) by adding 0.2 (mg dl-1) to serum creatinine. A pharmacokinetic study was performed during the first cycle of the chemotherapy. Blood samples were obtained at 10 points within 24 hours. The observed AUC of carboplatin and the observed carboplatin clearance were calculated. Results: Inulin clearance was estimated in 28 cancer patients. Estimation of renal function with adjusted 24-h Ccr and estimated GFR equation (eGFR) were unbiased [mean prediction error (MPE) = -2.3%, 5.2% respectively] and acceptably precise [root mean squared error (RMSE) = 23.7%, 25.7% respectively], whereas non-adjusted Ccr and the Cockcroft-Gault equation overestimated GFR (MPE = 24.2%, 12.5% and RMSE = 37.2%, 32.7% respectively). Observed carboplatin clearance was proportional to GFR in range of renal function in this study (r = 0.903) and we verified the linearity. Non-renal clearance of carboplatin in Japanese cancer patients was 5.6 (ml min-1). Conclusions: 24-h Ccr adjusted by adding 0.2 (mg dl-1) to serum creatinine and eGFR were useful in assessing renal function for carboplatin dosing. It was suggested that non-renal clearance of carboplatin in Japanese cancer patients was less than 25 (ml min-1). No significant financial relationships to disclose.

Abstract
BACKGROUND AND OBJECTIVE Calcium channel blockers (CCBs) have been widely used for the treatment of hypertension and angina pectoris. It is presumed that CCBs decrease the lower esophageal sphincter pressure and as a result, the risk of gastrointestinal disease may be increased. Since the prevalence of gastrointestinal diseases has increased in elderly patients, it is possible that treatment with CCBs may have contributed to this increase. Therefore, we considered that the risk of exacerbating gastrointestinal disease among elderly patients by CCBs can be estimated by using the prescription ratio of antisecretory drugs as an outcome. METHOD We hypothesized that patients who are prescribed CCBs would increase the use of antisecretory drugs involving H(2)-receptor antagonists and proton pump inhibitors (PPIs). From January 2001 to December 2005, a dynamic retrospective cohort study was performed at three community pharmacies in Nagasaki city, Japan, to assess the use of antisecretory drugs following treatment with CCBs among elderly patients. The correlation of initiation of antisecretory drugs treatment to maintenance therapy with PPIs was determined by the Cox proportional hazards model. RESULTS The proposed study includes 303 patients prescribed CCBs and 258 controls. During the study period, 138 patients prescribed CCBs and 66 controls were initiated by giving antisecretory drugs; the hazard ratio was 1.40 (95% confidence interval 1.21-1.63). Eighty two patients taking CCBs and 32 controls were initiated by the maintenance therapy with PPIs; the hazard ratio was 1.48 (95% confidence interval 1.21-1.83). CONCLUSION Patients who simultaneously initiated the use of antisecretory drugs with CCBs could not be found. Therefore, antisecretory drugs have not been used to prevent the gastrointestinal diseases caused by CCBs. The results obtained in this study suggest that the risk of gastrointestinal disease could be increased by long-term treatment with CCBs for elderly patients.

Abstract
5118 Background: Steroid hormone have been implicated in playing a fundamental role in pathogenesis of prostate cancer and several studies have reported an association between clinical outcome and polymorphism of genes involved in steroid metabolism. Recently we observed that polymorphic enzyme CYP17 which influences the rate-limiting steps in androgen biosynthesis was associated with overall survival. However, the effect of genetic variation on the transport of steroid hormones remains unknown. The purpose of this study was to evaluate the association between clinical outcomes in patients with androgen independent prostate cancer, and polymorphism in the SLCO1B3 gene that are potentially important in the differential uptake of steroid hormones. Methods: One hundred seventy nine white Caucasian patients with androgen independent prostate cancer were enrolled in this study. The duration of survival was computed from the date of prostate cancer diagnosis until the date of death or last follow-up. The SLCO1B3 polymorphism (-334 T>G) was analyzed using an automated sequencer. Results: The T allele (TT or TG) and G allele (GG) frequency of SLCO1B3 among all patients was 0.16 and 0.84, respectively. The frequency of the SLCO1B3 genotype was similar in patients and healthy volunteer. No significant differences were observed in the frequencies of the SLCO1B3 genotype in relation to categorized Gleason scores and age at diagnosis. Interestingly, the median survival was significantly longer in 134 patients with the SLCO1B3 G allele (8.4 years) genotype than 45 patients carrying at least one T allele (6.4 years) genotype (hazard ratio=1.58, 95%CI: 1.13 - 2.26, p=0.0105 by Logrank test). Similarly, the survival probability at ten years (22.9% in T allele vs 41.1% in G allele) is observed. Conclusions: Our results indicate that the SLCO1B3 polymorphism is associated with overall survival in white Caucasian patients with androgen independent prostate cancer. Large population-based studies are needed to confirm these results. No significant financial relationships to disclose.

Abstract
The effect of acute renal failure (ARF) induced by ischemia/reperfusion (I/R) of rat kidney on the expression of organic anion transporters (OATs) was examined. The level of serum indoxyl sulfate (IS), a uremic toxin and substrate of OATs in renal tubules, shows a marked increase with the progression of ARF. However, this increase was significantly attenuated by ingestion of cobalt. The level of mRNA and protein of both rOAT1 and rOAT3 were markedly depressed in the ischemic kidney. The uptake of p-aminohippuric acid (PAH) and estrone sulfate (ES) by renal slices of ischemic rats was significantly reduced compared to control rats. Renal slices taken from ischemic rats treated with cobalt displayed significantly elevated levels of ES uptake. Cobalt intake did not affect PAH uptake, indicating the functional restoration of rOAT3 but not rOAT1. The expression of Na(+)/K(+)-ATPase was markedly depressed in the ischemic kidney, suggesting that the inward Na(+) gradient in renal tubular cells had collapsed, thereby reducing the outward gradient of alpha-ketoglutarate, a driving force of both rOATs. The decreased expression of Na(+)/K(+)-ATPase was significantly restored by cobalt treatment. Our results suggest that the downregulation of renal rOAT1 and rOAT3 could be responsible for the increase in serum IS level of ischemic rats. Cobalt treatment has a significant protective effect on ischemia-induced ARF, being accompanied by the restoration of rOAT3 and/or Na(+)/K(+)-ATPase function.

Abstract
To explore retrospectively the relationships between paclitaxel pharmacokinetics and three known, non-synonymous single-nucleotide polymorphisms (SNPs) in SLCO1B3, the gene encoding organic anion transporting polypeptide (OATP)1B3. Accumulation of [(3)H]paclitaxel was studied in Xenopus laevis oocytes injected with cRNA of Oatp1b2, OATP1A2, OATP1B1, OATP1B3, OAT1, OAT3, OCT1, and NTCP. The 334T>G (Ser112Ala), 699G>A (Met233Ile), and 1564G>T (Gly522Cys) loci of SLCO1B3 were screened in 475 individuals from five ethnic groups and 90 European Caucasian cancer patients treated with paclitaxel. Only OATP1B3 was capable of transporting paclitaxel to a significant extent (P=0.003). The 334T>G and 699G>A SNPs were less common in the African-American and Ghanaian populations (P<0.000001). Paclitaxel pharmacokinetics were not associated with the studied SNPs or haplotypes (P>0.3). The studied SNPs in SLCO1B3 appear to play a limited role in the disposition of paclitaxel, although their clinical significance in other ethnic populations remains to be investigated.
